⚠️ Common Signs of Failure

• No response or intermittent operation
• Incorrect signal or warning
• Overheating or burnt terminals
• Corrosion or water intrusion

🛠️ Service Notes

• Isolate the batteries before disconnecting anything, and label the leads as they come off so they go back on the correct terminals
• Check the replacement matches the original for contact rating and action; a switch that cannot carry the load will burn its contacts
• Clean the terminals, make the connections tight and dry, and support the loom so it is not left hanging on the switch body
• Refit the seal, boot or gland that came with the switch — water getting in behind a switch is the usual reason they fail afloat
• Work the switch through its full travel and confirm the circuit behaves correctly, including any interlock or alarm function, before the engine goes back into service
